Pelargonium plant named ‘Cante Laver’

ABSTRACT

A  pelargonium  cultivar particularly distinguished by single-type lavender flowers with white eyes, medium to large umbrella-shaped inflorescences, medium-green to grass-green foliage with very weak zonation, a compact to medium-sized with a spreading, prostrate to semi-trailing plant habit, a very well-branched and dense plant habit, and an early to mid-season flowering response, is disclosed.

Genus and species: Pelargonium×hortorum×Pelargonium tongaense hybrid.

Variety denomination: ‘Cante Laver’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of pelargonium, botanically known as Pelargonium×hortorum×Pelargonium tongaense hybrid, and herein after referred to by the cultivar name ‘Cante Laver’. The new cultivar was a product of a planned breeding program which had the objective of creating new varieties having various colors and a moderately compact and well-branched plant habit. The female parent was the proprietary dark red-flowered ‘8961-2’ (unpatented) pelargonium, and the male parent was the proprietary dark red-flowered ‘9104-1’ (unpatented) pelargonium. The hybridization occurred in October 2001 and the resulting seeds were sown in a greenhouse in February 2002. A single plant selection was chosen for further evaluation and for asexual propagation in the Summer of 2003, in Gilroy, Calif.

The new cultivar was created in 2001 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. over a two-year period. ‘Cante Laver’ has not been observed under all possible environmental conditions. ‘Cante Laver’ has also been trialed at Gilroy, Calif. and Hillscheid, Germany. ‘Cante Laver’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Canada on Mar. 29, 2005, and with the European Union on Sep. 20, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal commercial practices in Hillscheid, Germany.

-   -   1. Single-type lavender flowers with white eyes;     -   2. A medium to large, umbrella-shaped inflorescence;     -   3. Medium-green to grass-green foliage with very weak zonation;     -   4. A medium-sized and compact plant habit;     -   5. A compact to medium-sized, with a spreading to prostrate to         semi-trailing plant habit;     -   6. A well-branched and dense plant habit; and     -   7. An early to mid-season flowering response.

DESCRIPTION OF THE PHOTOGRAPHS

This new geranium plant is illustrated by the accompanying photographs which show the overall plant habit, including inflorescences, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 22-week-old plant grown from outdoors from rooted cuttings in the mid-Summer under conditions which approximate those generally used in commercial practice.

FIG. 1 shows the overall plant habit, including inflorescences, buds and foliage of the plant.

FIG. 2 shows a view from above of a 45-cm diameter tub holding 3 flowering plants.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Cante Laver’. The data which defines these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on un-pinched, 13-week-old plants grown in 12-cm pots in a greenhouse in late May 2005. The color readings were taken under natural light in the greenhouse in May 2005. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
